Bekannt ist, dass der Lenkwinkel mit einer Codescheibe und einem die Codescheibe abtastenden optischen Sensor erfasst wird, wobei der optische Sensor ortsfest und die Codescheibe an der Lenkwelle fixiert ist, oder umgekehrt.Known is that the steering angle with a code disk and a the code disk scanning optical sensor is detected, wherein the optical sensor stationary and the code disc is fixed to the steering shaft, or vice versa.
Mit
der wachsenden Verbreitung von Regelsystemen zur Regelung der Fahrdynamik
von Kraftfahrzeugen hat die Bedeutung von Lenkwinkelsensoren erheblich
zugenommen. Derartige Sensoren haben die Aufgabe, ein Signal zu
erzeugen, welches kennzeichnend für den Lenkwinkel bzw. die Lenkwinkeländerung
eines Fahrzeugs ist. Hierzu ist in der Regel ein Codierelement,
insbesondere eine Codescheibe starr mit der Lenkwelle verbunden.
Der Codescheibe ist ein optischer Sensor zugeordnet, welcher gegenüber dem
Chassis bzw. der Lenkwelle fixiert ist, und welcher in der Lage
ist, den Code der Codescheibe zu lesen. Dabei sind an der Scheibe, z.B.
in Form von Strichen oder Auskerbungen, Markierungen angebracht,
welche abgetastet werden. Der optische Sensor kann aus einer Leuchtdiode

Mit derartigen Anordnungen können der absolute Lenkwinkel, die Lenkrichtung, die Lenkgeschwindigkeit und die Lenkbeschleunigung relativ präzise ermittelt werden, jedoch sind diese Daten, z.B. für eine elektromechanische Lenkhilfe (EPAS), zu wenig. Darüber hinaus werden die Richtung und die Größe des Lenkdrehmoments benötigt.With such arrangements can the absolute steering angle, the steering direction, the steering speed and the steering acceleration can be determined relatively precisely, however are these data, e.g. For Electromechanical power steering (EPAS), too little. Furthermore be the direction and the size of the steering torque needed.
Die
bekannten optischen Verfahren haben alle die Eigenschaft, dass die
für die
Drehmomentmessung notwendige Genauigkeit der Messung des Differenzwinkels
zwischen Ein- und Ausgangswelle eines Torsionsstücks in einer Größenordnung
kleiner als 0,05° liegen
muss. Dies stellt die abbildende Optik vor Probleme, da die Messung
der Lage von Strukturkanten aufgrund der direkten optischen Abbildung auf
den Detektor deutlich besser sein muss, als der Abstand der Pixel
der verwendeten optischen Sensorarrays. Die Messung des Drehmoments
an den beiden Enden eines Torsionsstücks mittels optischer Sensoren
ist z.B. aus der WO 99 09 385 A1 bekannt. Die Abtastung eines Musters
an einer Encoderscheibe mittels einer Optik ist z.B. aus der
Analoge optische Verfahren, wie oben erwähnt, sind für die Messung kleiner Verdrehwinkel in Lenksystemen zur Bestimmung des Drehmoments weniger geeignet, da sie weniger robust sind. Vor allem bei der Verwendung des Sensors an einem Lenkgetriebe im Motorraum besteht, wie bereits erwähnt, durch die dort herrschenden höheren Temperaturen und durch den Anfall von Öl, Fett und Staub die Gefahr einer Störung eines derart hoch auflösenden analogen optischen Systems.analog optical methods, as mentioned above, are for the measurement of small angles of rotation in steering systems for determination less suitable because they are less robust. In front especially when using the sensor on a steering gear in the engine compartment exists, as already mentioned, by the ruling higher ones Temperatures and by the accumulation of oil, grease and dust the danger a fault such a high-resolution analog optical system.
Optische Sensoren im Motorraum sind dann geeignet, wenn sie digital und mit grober Auflösung arbeiten. Analoge optische Sensoren mit hoher Auflösung erscheinen aber weniger geeignet.optical Sensors in the engine compartment are suitable if they are digital and with rough resolution work. However, analog optical sensors with high resolution appear less suitable.

Verfahren zur Drehmomentmessung arbeiten üblicherweise mit magnetischen Multipolrädern und
